Inlays may be used as single-tooth restorations for proximo-occlusal or gingival lesions with minimal to moderate extensions
Shillingburg page 1
An inlay may be defined as a restoration which has been constructed out of mouth from gold, porcelain, or other material & then cemented into the prepared cavity of a tooth.
William McGehee pg410
The cast metal restoration is versatile and is especially applicable to Class II onlay preparations. The process has many steps, involves many dental materials, and requires meticulous attention to prepration.
Tooth treatment planned to be restored with an intracoronal restoration, but the decay or fracture is so extensive that a direct restoration, such as amalgam or composite, would not be able to sustain or bear forces.
Additionally, when decay or fracture incorporate areas of cusp or remaining tooth structure that undermines perimeter walls of a tooth, an onlay might be indicated.

The simplicity of bonding can be misleading. The technique undoubtedly can be misused, not only by an inexperienced clinician but also by more experienced orthodontists who do not perform procedures with care.
Success in bonding requires understanding of and adherence to accepted orthodontic and preventive dentistry principles.
The advantages and disadvantages of bonding versus banding of different teeth must be weighed according to each practitioner’s preferences, skill, and experience.
Bonding should be considered as part of a modern preventive package that also includes a strict oral hygiene program, fluoride supplementation, and the use of simple yet effective appliances. In other words, complicated mechanics with abundant use of coil springs and multilooped arches lends itself less well to bonding and easily can compromise the integrity of tooth enamel and gingival tissues around brackets on small bonding bases.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. INTRODUCTION
came back in modern dental history in late
ninteenth century as an esthetic means of restoring carious
leisons.
CERAMIC INLAYS
4. Unfortunately the use of porcelain inlays was halted by too
high failure rate because of poor marginal fit and the easily
wash out conventional cement.
5.
– Porcelain inlays tentatively reintroduced in 1980s as a
result of several technological developments:
advances made in refractory investments.
the use of silane coupling agents.
the use of composite resin cements.
improved bonding technique.
6. Case selection determines the medium or long term
success of ceramic inlays/ onlays.
7. CASE SELECTION
Case selection can be done on
basic rules like:
To be indicated for
medium –level damage to
vital molars & premolars.
Must be prepared to leave
an outer enamel margin for
reliable seal.
8. Prepared margins must
never coincide with occlusal
contacts as it is a root cause
of medium term failures.
9. extensive unsupported over hangs must be avoided
because it may lead to fractures.
contraindicated in parafunctional activity.
ease to access the cavity for preparation, making
impressions and bonding.
contraindicated in short clinical crown.
10. Modifiable adverse clinical conditions
Certain adjustments can often improve status of tooth
making ceramic inlays /onlays as a viable option like
A very DEEP CAVITIY with insufficient remaining dentin
thickness <0.5 m.m can be dealt with using a calcium
hydroxide lining as a pulpal dressing and covered with resin
modified glass ionomer cement.
SUBGINGIVAL MARGINS may be dealt with by partial
gingevectomy, thus rendering them supragingival for
impression making and bonding
11. Ceramic inlays or onlays ???
prefer to prepare an inlay cavity in view of the cuspal
reinforcement effect by bonding
prefer to cuspal overlay in clinical situations like;
• margins located away occlusal contacts, on the labial
and lingual surfaces.
• esthetically onlays are superior
and more reliable seal.
12. Tooth preparation
Both inlays /onlays differs from that of cast metal onlays/
inlays due to properties of ceramics.
13. INLAYS
Following modifications to a conventional inlay
for ceramic inlays are:
a proximal cavity with no
slice cut or bevel edge.
axial walls with a roughly
10 degrees angle of taper.
16. occlusal margins may not coincide with occlusal
contacts.
margins should be prepared to a 90 degree
cavosurface line angle; alternatively they should
present a hallow ground chamfer in an attempt to
create an ‘invisible’ margin.
17. ONLAYS
Cuspal overlying should allow a clearance of at least 1.5mm
preferably 2mm.
All cuspal angles should be rounded and margins should
consist of a shoulder with a rounded internal line angles or
deep chamfer.
18. Tapered round-end diamond instuments and olive-shaped
or sperical instrument designed for hollow ground
chamfer are used for inlays and onlays .
19. Fabrication of inlay/onlays
IMPRESSION MAKING AND DUPLICATES
Impressions of supragingival cavity preparations
are
made with hydrocolloids or silicones. Addition silicones are
material of choice.
Fabrication of ceramic inlays/ onlays often requires
preparation of duplicate dies of refractory material. Usage of
addition silicones aids in accurate duplicate casts.
20. TEMPORIZATION
Temporization is an indispensable stage ,oversight here can
affect pulp and/ or final adhesion of ceramic restoration.
Best solution consists of direct, chair side creation of light –
cured resin inlays/ onlays after lubrication of teeth. After
trimming and adjusting the margins and occlusal contact
sites resin inlay luted with eugenol free temporary cement
21. TRYIN
Try in allows the fit of the inlay or onlay to be tested.
This stage requires care and accuracy owing to the
fragility of the ceramic retorations prior to bonding.
The inlays / onlays are inserted using a small globule of
wax of low melting point attatched to a plastic instrument
handle ,or using a placing instrument such as ACCUPLACER, HU-FRIEDY.
22. Both try in and bonding are facilitated if a vertical
stabilization groove has been incorporated in
preparation
Adjustments of interproximal contact areas, and any
areas of friction on internal surface should be done.
23. INTERPROXIMAL AJUSTMENTS
A sheet of carbon paper may be used for detecting the
contact area or better still proximal surface can be
stained with pillar-box red dissolve in chloroform.
Corrrection should be carried out slowly ,using
aluminous silicone wheels or cups.
24. FRICTION ON THE INTERNAL SURFACE
A white silicone fluid (FITCHECKER,GC) is used for
detection of discrepancies and adjusted with red-banded
medium speed diamond instruments.
Not recommended to check occlusal contact prior to
bonding ,causes fracture of inlay/ onlay .
If necessary to check a silicone fluid
film(MEMOSIL,BAYER) should be used to soften occlusal
impact.
26. CHOICE OF CEMENT
If the inlay/ onlay >2mm thickness the cement of choice
will be dual cure resin cement.
If >3mm thickness the cement of choice is
autopolymerizing resin cement.
Resin cements should be used in conjugation with
appropriate dentin –enamel adhesives.
27. CHOICE OF COLOR OF CEMENT
The choice of resin cement color is an important
consideration.
Considering the thickness of restoration, some prefer luting
cement to be only faintly coloured and translucent enough
to bring out the natural color of dentin and enamel.
This takes into account try in pastes are used to match with
tooth.
28. VISCOCITY OF CEMENT
Microfilled composite cements are used previously because of the
fluidness and fineness of the cement layer but medium term
breakdown ,wear and hydrolysis occurs at weak point of inlays/ onlays
bonded with cement .
So highly filled and viscous microhybrid composite cements are used
for bonding . As it is less fluidic requires ultrasonic placement.
MARGINAL FIT
The more accurate the margins the smaller the thickness devoted to
the composite cementend the more marginal defects will be.
The accuracy of investments and refinements of ceramics and
composite cements permit mean thickness values of 0.05 nanomicrons
29. Margin failure results from:
Wear and loss of the composite
Insufficient thickness of ceramic
Microscopic cracks in the ceramic
Microsropic distortion of the margins due to
concentration of stress
Coincidence of margins with functional occlusal
contact sites
30. QUALITY OF ADHESION AND SEAL
Adhesion and seal are certainly associated ,but can evolve
completely independently of each other. Both can effect on
the success of inlays/ onlays.
Debonding occurs due to marginal leakage from a defect of
the margin ,such as splitting , wear at the interface a poor fit
etc, or from a cervical margin bonded onto the dentin or
cementum.
32. Rubber dam application
Removal of provisional inlays and cavities are cleaned with hand
instruments, with ultrasonic instruments and finally with air-powder
abrasive device to remove contaminants and temporary cement.
Best for luting is usage of single-component enamel-dentin adhesive
and dual cure luting composite.
Inlays/ onlays while sandblasting are protected externally by wax
Internal aspect of inlay/ onlay is etched for 90 secs with10% of HF acid ,
rinsed in running water dried and silanated. After evaporation of the
silane ,primer is applied and light cured.
Tooth surface first disinfected with chlorexidine gel, dried and etched
with all etch technique. Two thin coats of one-step primer applied and
light cured.
33. Composite mixed and applied onto preparation, inlay is inserted and excess
cement is removed with brush and dental floss.
Inlay is secured in position and light cured for 1 min, small excesses can
removed with bade and more excesses is removed with fluted bur.
After cleaning and checking the occlusion one important step before
polishing ,namely sealing the margins and surface of the restorations.
For that purpose all accessible limits are etched for 10 sec, rinsed ,dried
,impregnated with a liquid resin and light cured for 20 seconds.
BLOCKING TUBULES WITH PROTECTIVE HYBRID LAYER and SEALING THE
MARGINS AND SURFACES are two very important steps for acheiving
excellent bonding.
Finally polished with silicone cup disks and lustered with diamond paste on a
prophylactic cup.
